FAQ : 安装过程中提示：On systemwide basis, the maximum number of SEMMNI is not correct……

在虚拟机中安装GBase 8c单机版时，第二步检查不通过。GBase 8c其他版本如出现此类错误，也可参照。

执行安装命令以及报错显示：

[omm@localhost simpleInstall]$ sh install.sh -w Gauss_234

[step 1]: check parameter

[step 2]: check install env and os setting

On systemwide basis, the maximum number of SEMMNI is not correct. the current SEMMNI value is: 128. Please check it.

The required value should be greater than 321. You can modify it in file '/etc/sysctl.conf'.

解决方案：修改参数配置

[root@localhost ~]# sysctl -w kernel.sem="250 85000 250 330"

kernel.sem = 250 85000 250 330
